get the whole trailing arm/hub/rotor/caliper assembly. it is very easy to do. but you'll have to re-align the rear end of the car after you do it. only tough part i had was gettin the Ebrake cables onto the damn hand brake. just takes some finesse

If you're on a tight budget, and ordering them through the mail you can save some money and get just the spindles, calipers and rotors from any 88-00 civic or 94+ teg. It's a little more of a pain in the ass to install because you need a special socket, and are wokring in a very tight space, but trailing arms are big, heavy and expensive to ship.
